I’ve been working with iOS since about 2008. I haven’t touched core data for about 10 years...it’s not worth the pain.

biggest problem with core data (imo) was they never ported the data controllers (nsobjectcontroller, nsarraycontroller, nstreecontroller etc) which makes dealing with core data much easier (to say nothing about the lack of bindings as used in appkit)

Take a look at NSFetchedResultsController, it gives you what you want from NSObjectController and NSArrayController, and there aren't really UI widgets on iOS where NSTreeController is appropriate like there are in AppKit.
